What is the Oracle 11g buffer cache?
The Oracle 11g buffer cache is a memory structure that stores recently used copies of database blocks that have been read from datafiles within the SGA (System Global Area). It is used to reduce physical I/O operations, which are a major bottleneck in database performance. When a query requires data, the buffer cache is consulted first. If the requested data is already in the cache, then it can be returned quickly. If not, the data is read from disk and kept in the buffer cache for faster retrieval the next time it is requested.

Will Social Security become insolvent?
No, although Social Security's long-term financial health is uncertain, it is unlikely that the program will become insolvent. Technically Social Security is an "sponsored institution," so it has protections that allow it to pay benefits even when the trust funds are depleted, if needed. The program is projected to see its costs rise in the coming years, and it will require some reforms to ensure it remains financially secure in the future. But it is unlikely to become insolvent.
